L ihc icii't thereby siiiiijiing the van (Tish '0 from migagcn the left hand end ofthe cylinder will be placed in communication with the outer air, while the right hand end will be placed in communication with the milk pail so that the operation will be reversed. This re-' ciproeating movement of the actuating piston is transmitted through the lever 39 to the pulsator valve and results in the operation of the pulsator as previously described. The milk flows only through the passages which are controlled 'by the pulsator valve and the actuating mechanism of thisvalve is entirely separate from the pulsator valve and not affected by the milk or the milk by this actuating mechanism. In order to clean the valve mechanism and connecting milk passages, it is therefore only necessary to clean the pulsator valve and connecting parts, which s readily done upon disconnecting the lever 39 from the valve and removing the latter from its cylinder.

It isobvious that the mechanical features of thepiilsatot' valve and its pneumatic actuating mechanism maybe modified in many respects without departing from the spirit of the invention, the consti'uctionshow'n being intended only to representthe best mode known to me of carrying the invention .into practice.

I claim as my invention: 1. In a milking machine, the combination of a pulsatoi valve which is exposed at both ends to the same pressure and which applies. suction intermittently, and a double-acting pneumatic motor separate from said valve and connected therewith for actuating the same, substant ally as set forth.

2, Ima-fni'illinga iachine, the coinbiiuitioii of a pulsator valve which is exposed at both ends to the same pressure, and a doulilcacting pneumatic motor separate from said valve and comprising an actuating cylinder .-.nd piston, a reversing valve and an escape mcnt inccl'ianisin connecting said piston with said reversing valve, substantially as set forth.

3. in a milking machine, the combination of a pulsator piston valve, an open-ended cylinder therefor in which said valve is exposed at both ends to the some pressure, a pncnmatic motor inde endent of said valve,

and means for connecting said valve with said motor, substantially as set forth.

4. The combination of a milk pail, a cover therefor, an open-ended valve cylinder an ranged on the cover and having both ends exposed to the atmosphere, said cylinder being provided with a suction port connecting said cylinder with the pail and with an air inlet port, an inspcctionchamber communieating with said cylinder and having a plurality of connections for individual teatcup tubes, and a pulsator valve arranged in said'cylinder and comprising heads which fit in the same and a reduced connecting portion forming a chamber for placing the inspection chamber in communication with the outer air, one said heads having an air inlet port for-placing the inspection chamber in communication with said air in let port of the cylinder, substantially as set forth.

5. In a milkings' imachinc, the combination of a pulsator valfve", apneumatically actuated piston and rod for operating the same, a cylinder in which said piston is arranged, a reversing valve for controlling the flow of the actuating fluid to the cylinder, a valve rod provided-with tappets, locking arms engaging said tappets, a releasing device for said arms, and reversing" springs acting on said-valve rod, substantially as set forth.

6. In a milking machine, the combination of a pulsator valve, a pneumatically actuated.

piston and rod for operating the same, a cylinder in Which said piston is arranged, a reversing valve for control-ling the flow of the actuating fluid to the cylinder, a valve rod provided with tappets, locking arms engaging said tappets, a rcleysing shoe secured to said piston rod and alternately engaging said locking arms, and reversing springs intcrposcd between said shoe and tappets and acting on said valve rod, substantiallydis set forth.
